This is the difference in the basic ideas of the two design institutes, and if the 601 Institute wants to make their project compete successfully, it will inevitably instill in everyone such an idea, don't listen to Song Lao, Song Lao is a big fool, he said it out of the blue, can his ones be realized?

Why did Deputy Director Wang ask such questions? Because such a problem must have spread, and now, Song Lao wants to dispel everyone's concerns.

"The canard layout has disadvantages, if the layout is static and stable, then its lift-to-drag ratio is not dominant, only the use of static and unstable layout, in order to give full play to its advantages of mobility and flexibility." Song Lao said: "Over the years, we have been studying the duck layout, accumulated a lot of experience, we want to relax the degree of tranquility, we are all experts, know that the wider this, then, our fighters will be more flexible, at the same time, it will also contain huge risks." ”

Song Lao finally said the most critical place, how do you overcome the problem of risk?

"Static aircraft, in our domestic military aircraft development, there is no theoretical basis and practical application, even the United States, the United Kingdom, these developed aviation industry powers, in the research and development of the third generation of fighters, but also only relax the stability of the static stability to zero, for us, this is a huge challenge, if our design problems, it will lead to the waste of previous efforts."

Speaking of this, Song Lao looked at the people around him and said, "So, we have prepared a plan in advance, if our technology is not up to the mark for the time being, we only need to reduce the area of the canard wing by half, so that it will change from a quiet and stable aircraft to a quiet and stable aircraft." This is our new plan, wait until our flight control system matures, and then improve to a static layout. ”

Whether this static stability or instability is mainly determined by the question of whether the center of lift and the center of gravity coincide, as long as you simply change the canard, you can change the position of the center of gravity, so that the center of gravity moves backward and coincides with the center of gravity.

As for the overcoming of technical problems, we have sufficient preparations, although our own standards are very high, but if we cannot meet the current standards, we still have a temporary replacement plan, in short, this project, that will be able to be perfected, and finally mature.

"As for the pulse-Doppler radar we need, it is also a key now, our country, without any experience, we have countless technical problems on a simple single-pulse radar." Song Lao continued: "And now, we already know that our problem is that we have the wrong route, when the Western world has begun to use digital circuits on a large scale, we are still using analog circuits, so this is also a shortcoming for us. ”

The 611 Institute builds airplanes, but they don't know how to build radars, and radars are still built by the corresponding brother units, so no one knows what problems will arise in the development of radars.

"We've partnered with Marconi to introduce their avionics system, and now, the doors of the Western world are open to us." Song Lao continued: "We can get the technology we need from the West, and besides, the brother units have always had this plan to introduce advanced pulse Doppler radar to equip the J-8 fighter, so that we will be wiped out." ”

How to solve the problem of radar in avionics? Song Lao's idea was to introduce, not to mention anything else, this kind of radar was originally intended to be introduced on the J-7, but in the end it was not negotiated, and the introduction of pulse Doppler radar and inertial navigation system was handed over to the 601 Institute and handed over to the J-8 project to be introduced.

Since it can be introduced to the outside world, it is completely okay to use it on your own fighters.

I really don't understand, why does the 601 Institute just cling to the existing technology and refuse to look forward?

Hearing this, the experts of the 601 Institute present all looked ugly.

The project of the Marconi company, which has been talked about for so long, what is the result? The superior said that if you don't want it, you don't want it, and you'd rather pay compensation than a deposit, and you don't plan to continue the project.

What you say now sounds good, waiting for the introduction, and many times, waiting and waiting will be yellow.

They are not as insistent as Tu Lao, they have always listened to the words of their superiors the most, and the superiors said that they would introduce it, and if the superiors said that they didn't want it, then they didn't want it.

How deep the water is in the middle, don't you know Old Song?

"What do we do in case we can't bring in this radar from abroad? Song Lao, you also said that almost all of our current electronic technicians are engaged in analog circuits, and there are not many who know digital circuits, and we want to develop them ourselves, which is impossible. ”

The international situation is changing, what if it is impossible to introduce it?

Hearing this question, Song Lao was stunned, he really hadn't thought of this.

"Our external channels are not limited to the Western world." Seeing that Song Lao couldn't answer, Qin Feng immediately picked up the conversation below: "We can also get it from other countries, for example, Persia is a good choice." ”

Now, a large-scale war is breaking out in the Middle East, this war has completely fed the domestic military industrial enterprises, those who make guns and tanks, are producing at full capacity, and now what everyone doesn't know is that even the batch of J-7 fighters ordered by Jordan was sent to Iraq by Jordan.

Persia is now the most arrogant, in their mouths, the United States is the Great Satan, the Soviet Union is the Second Satan, in short, they are not good things, they have offended both the United States and the Soviet Union, so that the source of Persian weapons can only rely on the country.

The Persian fighters, which used to be Tomcats of one water, looked very chic, and the Tomcat fighters, the most powerful of which is the combination of AWG-9 radar and Immortal Bird missiles, is simply an incomparable existence.

Now, not many of their fighters can operate, because of the lack of parts, most of them are scrapped, and now, the Persian side must also lack fighters, even if it is used in a barter way, it should be able to get back the Tomcat and its corresponding radar equipment from Persia, just like the cooperation with the Egyptian side.

Now, what is the principle of pulse-Doppler radar, even the basic block diagram, I am afraid that many people do not understand, if there is a physical object in front of you, it is much easier, not to mention, this radar is also one of the most advanced radars of this era.

In short, as long as you think of a way, there will be, in the face of a problem, you don't use your brains to figure out a way, are you still waiting for pie to fall from the sky?

Qin Feng's temporary interjection immediately provided Song Lao with ideas: "Yes, we can find Persia or Jews, in short, there will definitely be a way." ”
